Bei Dampfheizungsverbindungen der Eisenbahnwagen gebräuchliche Schläuche leiden erfahrungsgemäfs, wenn man sie über Rohrstutzen schiebt und mittels durch Schrauben zusammendrückbarer Schellen festprefst, um Ausblasen des Dampfes sicher zu verhüten. Durch die vereinigte Wirkung der Pressung und der Hitze des Dampfes wird der Gummi sehr bald weggequetscht und der Schlauch unbrauchbar. Experience has shown that hoses commonly used for steam heating connections on railroad cars suffer, if you push them over pipe sockets and press them into place by means of clamps that can be compressed by screws Safely prevent the steam from being blown out. Through the combined effect of the pressing and the heat of the steam soon squeezes the rubber away and makes the hose unusable.
Gleiches gilt von jedem stärkeren, um erfolgreich abzudichten, immer übermäfsig zu bemessenden Prefsdruck, sei es, dafs das Schlauchende einem Druck zwischen zwei Kegelflächen ausgesetzt wird, sei es, dafs man (bei dünneren Schläuchen) das Schlauchende umbiegt und an der Umbiegungsstelle einem starken Prefsdruck durch Schraubhülsen oder dergleichen aussetzt.The same applies to every stronger one, in order to seal successfully, always excessively measuring pre-pressure, be it that the end of the hose is subject to a pressure between two Conical surfaces is exposed, be it that one (with thinner hoses) the end of the hose bends and at the bend point a strong pre-pressure through screw sleeves or suspends like that.
Bei der den Gegenstand der Erfindung bildenden Schlauchverbindung ist, um jeden weiteren nachtheiligen Prefsdruck zu vermeiden, der elastische Schlauch in die Anschlufshülse so eingeschoben, dafs die Dichtung, ohne Einklemmen der Schlauchenden mittels Schellen, Sch raubhülsen oder Stopfbüchsen, lediglich durch den Innendruck der durch den Schlauch geführten Druckflüssigkeit herbeigeführt wird. Der Schlauch bleibt hierbei in der Anschlufshülse (wenn nicht sonstige Umstände seine Drehbarkeit behindern) frei drehbar und wird durch ein geeignetes Mittel gegen Längsverschiebung in der Hülse gesichert.In the hose connection forming the subject of the invention is to each To avoid further detrimental pre-pressure, insert the elastic hose into the connection sleeve inserted in such a way that the seal, without pinching the hose ends by means of clamps, Screw sleeves or stuffing boxes, only through the internal pressure of the hose guided hydraulic fluid is brought about. The hose remains in the connection sleeve (unless other circumstances hinder its rotation) freely rotatable and becomes secured against longitudinal displacement in the sleeve by a suitable means.
Fig. r und 2 zeigen im Längsschnitt zwei Ausführungsformen einer solchen Schlauchverbindung. FIGS. R and 2 show, in longitudinal section, two embodiments of such a hose connection.
Mit dem Rohrstück a, Fig. 1, zur Verbindung der Dampfleitungen zweier Wagen sind die zur Aufnahme der Schlauchenden c dienenden Hülsen b in einem Stück gegossen und im Knie mit einem zur Dampfwasserableitung dienenden Schraubventil e versehen. Die Wandstärke der Schlauchenden ist eine so grofse, dafs die Enden in sich selbst stabil genug sind, um bei nachlassendem oder aufhörendem Innendruck nicht in sich selbst zusammenzufallen, und um andererseits gegen Verschiebung nach Längsrichtung in der Hülse durch ein geeignetes Anschlagmittel gesichert werden zu können. .With the pipe section a, Fig. 1, for connecting the steam lines of two cars, the sleeves b serving to accommodate the hose ends c are cast in one piece and provided in the knee with a screw valve e serving to drain off steam water. The wall thickness of the hose ends is so great that the ends are inherently stable enough not to collapse on themselves when the internal pressure drops or ceases, and on the other hand to be able to be secured against displacement in the longitudinal direction in the sleeve by a suitable sling. .
Zu diesem Zwecke sind sowohl in Fig. 1 als in Fig. 2, welch letztere ein den Dampfstutzen der einzelnen' Wagen entsprechendes Rohrstück darstellt, die Enden der Hülsen wulstförmig, und innen liegt eine Ringnuth b1, jirni einen aufgeschnittenen weichen Metallring d nacli Einstecken des Schlauchendes als Anschlagmittel für den Schlauch einbringen zu können.For this purpose, both in Fig. 1 and in Fig. 2, the latter representing a piece of pipe corresponding to the steam nozzle of the individual car, the ends of the sleeves are bead-shaped, and inside there is a ring groove b 1 , jirni a cut, soft metal ring d after insertion to be able to bring in the hose end as a lifting device for the hose.
Jedes sonstige geeignete Anschlagmittel kann aber auch an Stelle dieses Anschlagringes treten.Any other suitable stop means can also take the place of this stop ring.
Fig. 3' zeigt die Art und Weise, wie der Anschlagring d in die Nuth bl eingebracht wird. Der Sprengring d ist, wie hier gezeigt, getheilt. Beim Einbringen in die Nuth wird er aus einander gebogen, darauf zunächst dasFig. 3 'shows the way in which the stop ring d is introduced into the groove b l . The snap ring d is, as shown here, divided. When it is introduced into the groove, it is bent apart, then first that
eine Ende des Ringes in die Nuth bl gedruckt, was die Elasticität des Gummischlauches zuläfst, und so allmählich der ganze Ring ei η ge- . bracht.one end of the ring is pressed into the groove b l , which allows the elasticity of the rubber hose, and so gradually the whole ring ei η. brings.
Um ein Herausziehen der Schlauchenden zu ermöglichen, stöfst man den Ring d durch Loch P mittels eines Werkzeuges heraus.In order to enable the hose ends to be pulled out, the ring d is pushed out through the hole P using a tool.
Da der eingelegte Sprengring d von nebensächlicher Bedeutung ist und nur das Herausfallen des Schlauches verhüten soll·, wenn im Innern des letzteren kein Druck vorhanden ist, so kann dieser Zweck auch durch andere bekannte Mittel erreicht werden.Since the inserted snap ring d is of secondary importance and is only intended to prevent the hose from falling out, if there is no pressure inside the latter, this purpose can also be achieved by other known means.
So kann z.B. eine Scheibe/, Fig. 4, mit zwei vorgesteckten Splinten gg denselben Zweck erfüllen oder· es braucht nur ein gabelförmiger Splint h, Fig. 5, dessen Enden Λ1 umgebogen sind, vorgesteckt zu werden- / Thus, for example a disk /, Fig. 4, with two pre-mounted split pins gg serve the same purpose or · it needs only a bifurcated split pin h, Fig. 5, the ends of which are bent Λ 1 to werden- pre-infected /
